Some programs are written in C++ some in LUA some in assembly. Kernal-mode is a type of access level for an exploit(loopholes or bugs where unsigned, or not varified with sony, code can be run) which enables ISO (or images of a UMD disc on the memory card) to be executed. Last of all Libungif was an attempted exploit was was proven almost conclusivly not ever to be usable on the psp. It involved loading a corrupted gif and having the psp freeze/lockup. People still post about the libungif bug as if it was an expoit, just ignore them and wait for the thread to be close/locked/deleted.

Edit: kernal mode also enables other features. Its pretty much free run with the psp as opposed the User Mode exploits which are much more limited. User Mode exploits for the most part cant be used to make downgraders i believe, or at least its very hard to. The new GTA save game exploit was user mode and many experienced programmers failed to make a downgrader. However an Eboot program, or a program that allows other programs to be run easily without use of an exploit for each one, is being made for 2.01+ firmwares using the GTA Exploit.

If anything i said was wrong or needs expanding on, please post a correction or comment

so the GTA save thing is an exploit...also i saw something about an over flow buffer thing...and i saw lots of posts on it about trying to do something with it while it restarts after being shut down? what is all that about?

Kernal is the opposite of user mode and user mode is that blue screen with all the options of photo music etc?

exactly how does a downgrader work? andwhat about the prog i saw that would make the psp think its a 2.01 when it is a 1.5? ok sorry if i sound like a noob just trying to learn the lingo before i try talkingabout stuff. LoL

thnaks McGravey!

what exactly does the EBOOT LOADER do?

i think it allows for the other programs to be ran easily, but how I do not know....

it creates almost a little shell for the programs to run in. If they were standalone they would have to be coded a little differently to be ran through the exploit. The overflow was another exploit used in 2.0 where a .tiff file could be embedded with code to gain partial access to kernals. This alowed a Eboot loader to be easily made. A downgrader also came out for 2.0, however i am not positive on if it used the .tiff overflow or not.

the shell is metophorical, as i do not know the correct name of what it would be called
